Announcements & Notices

Add your workweeks, new hires, other announcements:



  • [djf] image decoding changes and image memory restrictions that affect 2.2. If your app can display many images using background-image, you may need to change it. (Contacts app?) See bug 1167336, for example.

(Alphabetical order)

Gaia Architecture Work

  • Telemetry library
  • Web app bridge (threads.js)
   - Stuck trying to identify why postMessage/BroadcastChannel is slow during startup.
   - Help needed with profiling Gaia apps please! :)
     - Tried B2G/ with pvt-eng build but fails
     - Trying to build B2G manually with MOZ_PROFILING=1, currently in VM world of pain.
  • Service workers
   - Tried different ways to communicate with SW, so far we realised that the best method is using http verbs, since they wake up the sw if it's dead.
   - Make some test to try the different caches system, in this case we tried successfully the custom cache.
   - Working on bugs and improvements on the library.
   - app:// protocol supported now in SW, but we found some bugs.
   - about:sw on settings app
  • SMS app conversion: will send a mail later today
  • Music app conversion
  • Contacts app conversion (prototype)
   - Moving views from Contacts App, now we can switch from one set of views to the other using a common service exposed in Threads.js! [1]. This will be useful when applying CustomCache.
   - This week we will be adding RenderCache (SW) to our prototype [2]
